[REBOL] rebol and lisp

[chaz]

What are the Rebol equivalents of Lisp's "atom?" and "quote" ? 

It appears that 
given two blocks 
mylist: [1 2 3] 
myotherlist: [4 5 6] 

first mylist 
is like
(car mylist) 

mylist: next mylist 
is like
(cdr mylist) 

insert/only mylist myotherlist 
is like
(cons myotherlist mylist)
